I noticed the same thing. "Hesitation" is a good way of putting it, everytime I want to parkour the character takes a split second to think about what I just told her to do.
Especially when climbing up walls the pause is very noticable. It's rather frustrating, isn't it?
It's really bad. Almost like being forced to use the launcher instead. Unfortunately I don't have it yet as I've just been exploring the city. Initiating a climb and jump across gaps feels really bad because of that hesitation.
